Although, if it's possible to arrange it, it's still better to do that
once and then use BEGIN/END_ALLOW_THREADS to avoid the overhead of
creating and destroying the temporary thread states:

Still, it's far, far easier than it used to be to handle the GIL
correctly from non-Python created threads.

Cheers,
Nick.
